Border Pine

Pinus strobiformis, also known as Chihuahua white pine, is a medium-sized white pine tree endemic to western Mexico in the Sierra Madre Occidental mountain range. It is typically a high-elevation pine growing mixed with other conifers in montane forest. It was formerly considered conspecific with Pinus reflexa (southwestern white pine) of the southwestern United States and Pinus stylesii of northeastern Mexico, but is now treated as distinct from these.
